Usage of food additives has become more and more frequent. Possible incorporation of genotoxic chemicals in dietary products, especially in food snacks, urges the need for their assessment. A total of 127 samples of food snacks, retailed on the Lebanese market, were screened for mutagenic activity towards Salmonella typhimurium strains TA98 and TA100 using Muta-ChromoPlate assay. The food items fall into two separate categories: the first category abides by high standards internationally approved; the second category is of a lower cost and a general poor quality. The first category was found to show no mutagenic activity even after exogenous S9- mix activation. However, 35.8% of the second category samples exhibited mutagenicity at 99% of significance, although without metabolic activation. These alarming results imply that drastic measures should be undertaken in order to protect the Lebanese consumers from being exposed to a potential risk of mutagenicity induced by such a dietary source.
